Serial No. 386,644.

Toiall whom it may concemi Be it known that I, JAMES HAMILTON, a

' citizen of the United States, and a resident of This invention relates to dumping buckets designed especially for sub-marine use, and has for its primary object to provide a suitable bucket simple in construction, effective in operation and durable in use, adapted to contain cement'and other substances, to hold said material securely in the bucket while it is lowered under the water, and to readily duinlp the contents of the bucket when desire Other objects relating to the specific construction and specialarrangement of the several parts of my invention will be understood from the accompanying drawings and followingvdescription, in which drawings igure 1 is an end elevation of a bucket embodying-my invention showing in dotted lines, the position assumedby the upper and lower trap doors when open; Fig. 2 is a vertical sectlon taken on the line 2-2 of Fig. 1 Fig. 3 is an end elevation of a modification of my invention; and Fig. 4 is an end elevation of the bucket shown in Fig. 3 with the trap doors opened.-

' Like characters of reference designate like parts in all the views.

. As illustrated in the drawings, 1- represents the bodyof the bucket, preferably provided on itsupper and lower ends with re-inforcing bands 2' extending around the ends of the body of the bucket. Trap doors 3 "are secured to the upper end of the bucket by means of hinges 4 and the inner or free edges of the doors may be providedwith lugs 5 having eyes adapted to be connected with the ends of a bridle chain 6. The bucket is provided with similar trap doors 7 connected y means'of hinges 8 to the lower portion of the bucket, and these doors are preferably provided with transverse bars 9 having upturned ends 10 to which are pivotally attached the lower ends of links 11. The upper ends of these links converge toward each other and are connected with the ends of a bail 12 b means of studs 13, which also have a siding engagement with slots 14 formed in uideways 15, these guideways being rivete or otherwise fixedly attached to the ends ofthe bucket. A supporting chain or cable 16 is connected with the bail 12 and provided with a ring 17 or other suitable device, by means of which the bucket may be readily'attached to a hoisting chain or cable, A dumping line 18, or other suitable means, is connected with the upper-central portion of the bridle chain 6 for the purpose of raising the top trap doors and dumping the bucket when desired. f

When the bucket is designed for use on land, the upper doors 3 may be dispensed with and the bucket supported by means of chains or cables 19 attached to stirrups 20 rigidly secured to the body of the bucket. The bail 12, and the means attached thereto for supportin the bucket, is also in such case dispensed wit and a lever 21 pivotally secured by any suitable means. such as a bolt 22, to the side of the bucket. The lever is provided with a slot 23 which engages the olt 13, and a keeper 24 issecured to the ,bucket in line with the free end of the lever 21, so as to hold that end of the lever securely in position when the doors of the bucket are closed. This keeper may consist of 'a stud or a sliding bolt or any other suitable means, adapted to' su port the free end of the lever inposition an ermit said end to be released therefrom at wi I. When the device is in use for sub-marine work, the bucket is sustained by means of the chain or cable 16 connected with the bail 12, and by means of said bail and the links 11 with the lower tra doors.7, thereby holding the doors in a closed position. The material to be used is then placed within the bucket, the up er doors 3 being first raisedby means of t e bridle chain 6, which is referably connectedwith the upper doors in ependently of the supportin cable 16. After the material has been place within the bucket the top doors 3 are closed and the bucket lowered into the water to the place desired. The bucket is dumped by means of the trippin cable 18, which raises the bridle chain 6 an opens the upper doors 3. When the upper doors are so opened, the entire weight of the bucket is supported on the tripping cable 18, and the cab e connected with the chain 16 is loosened so as to relieve said chain from the weight of the bucket and-its contents, and when said cable is loosened the weight of the bucket dumps itself because of the material in the bucket forcing 0 en the lower doors thereof. After the buc et has been dumped in this manner, the tripping is raised in the water closes the upper doors 3, While the pull on the chain 16 in raising the bucket closes the lower doors 7 because of the connection between said chain and doors, consisting of the bail 12 and the connecting links 11. After the bucket has been raised above the water, it may be refilled and operated in the manner already described.

When the construction shown in Figs. 3 and 4 is used for land work, the bucket is filled in the usual manner, and conducted by means of suitable hoisting apparatus to the lace desired, and is dum ed by releasing the ee end of the lever 21 om the keeper 24. When that end of the lever is released from the keeper, the weight of the material in the bucket forces downward the lower doors 7 and spreads the links 11, as shown in Fig. 1. After the bucket is dumped, the lower doors are closed by raising the free end of'the lever 21, which carries with it the links 11 and doors 7 connected therewith, and the parts are held in position by bringing the free end of the lever in engagement with the keeper 24. If desired, especially for small buckets used for land urposes, one of the doors and connecting lin k may be dispensed with and the remaining door extended across the entire bottom of the bucket.

Other changes may also be made in constructing a bucket in accordance with my invention, without departing from the scope thereof.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:

1. A dumping bucket comprising a body,

trap doors hinged to the lower portion of said body, vertical guideways secured to said body, links secured at their lower end to said body, vertical guideways secured to the opposite sides of said body, links secured at their lower end to said doors and having a sliding engagement with'said guideways, a bailconnected with the upper .end of said links, supporting means connected therewith, doors hinged to the upper part of said body, and supporting means-connected with the free ends of the upper doors independently of the first named su porting means.

3. A dumping buc et comprising'a body,

trap doors hinged to the lower portion of said body, links pivotally connected at their lower ends to said .doors, a bail connected with the upper ends of said links, a supporting connection attached to said bail, trap doors hinged to the upper portion of said body, and supporting means connected with thefree ends of the ently of the first name su porting means.

In testimony whereof Iv ave'signed my name to this specification in thepresen'ce of two subscribing witnesses. JAMES HAMILTON. [L s2] Witnesses:
